List of all members.

## Detailed Description

An interface for packing cells.

CellLayout is an interface to be implemented by all objects which want to provide a TreeView::Column-like API for packing cells, setting attributes and data funcs.

## Member Function Documentation

void Gtk::CellLayout::add_attribute | ( | CellRenderer& | cell,
|  | const Glib::ustring & | attribute,
|  | const TreeModelColumnBase& | column |
| ) |  |  |

void Gtk::CellLayout::add_attribute | ( | const Glib::PropertyProxy_Base & | property,
|  | const TreeModelColumnBase& | column |
| ) |  |  |

void Gtk::CellLayout::add_attribute | ( | CellRenderer& | cell,
|  | const Glib::ustring & | attribute,
|  | int | column |
| ) |  |  |

Adds an attribute mapping to the list in cell_layout.

The column is the column of the model to get a value from, and the attribute is the parameter on cell to be set from the value. So for example if column 2 of the model contains strings, you could have the "text" attribute of a Gtk::CellRendererText get its values from column 2.

Since gtkmm 2.4:

Parameters:

  | cell | A Gtk::CellRenderer.
  | attribute | An attribute on the renderer.
  | column | The column position on the model to get the attribute from.

virtual void Gtk::CellLayout::add_attribute_vfunc | ( | CellRenderer* | cell,
|  | const Glib::ustring & | attribute,
|  | int | column |
| ) |  |  | `[protected, virtual]`

static void Gtk::CellLayout::add_interface | ( | GType | gtype_implementer | ) | `[static]`

void Gtk::CellLayout::clear | ( |  | ) |

Unsets all the mappings on all renderers on cell_layout and removes all renderers from cell_layout.

Since gtkmm 2.4:

Reimplemented in Gtk::ComboBoxEntryText, and Gtk::ComboBoxText.

void Gtk::CellLayout::clear_attributes | ( | CellRenderer& | cell | ) |

Clears all existing attributes previously set with set_attributes().

Since gtkmm 2.4:

Parameters:

  | cell | A Gtk::CellRenderer to clear the attribute mapping on.

virtual void Gtk::CellLayout::clear_attributes_vfunc | ( | CellRenderer* | cell | ) | `[protected, virtual]`

virtual void Gtk::CellLayout::clear_vfunc | ( |  | ) | `[protected, virtual]`

Glib::ListHandle<const CellRenderer*> Gtk::CellLayout::get_cells | ( |  | ) | const

Return value: a list of cell renderers.

Returns:
  A list of cell renderers.

Since gtkmm 2.12:

Glib::ListHandle<CellRenderer*> Gtk::CellLayout::get_cells | ( |  | ) |

Return value: a list of cell renderers.

Returns:
  A list of cell renderers.

Since gtkmm 2.12:

const GtkCellLayout* Gtk::CellLayout::gobj | ( |  | ) | const`[inline]`

Provides access to the underlying C GObject.

Reimplemented from Glib::Interface.

Reimplemented in Gtk::CellView, Gtk::ComboBox, and Gtk::ComboBoxEntry.

GtkCellLayout* Gtk::CellLayout::gobj | ( |  | ) | `[inline]`

Provides access to the underlying C GObject.

Reimplemented from Glib::Interface.

Reimplemented in Gtk::CellView, Gtk::ComboBox, and Gtk::ComboBoxEntry.

void Gtk::CellLayout::pack_end | ( | CellRenderer& | cell,
|  | bool | expand = `true` |
| ) |  |  |

Adds the cell to the end of cell_layout.

If expand is `false`, then the cell is allocated no more space than it needs. Any unused space is divided evenly between cells for which expand is `true`.

Note that reusing the same cell renderer is not supported.

Since gtkmm 2.4:

Parameters:

  | cell | A Gtk::CellRenderer.
  | expand | `true` if cell is to be given extra space allocated to cell_layout.

virtual void Gtk::CellLayout::pack_end_vfunc | ( | CellRenderer* | cell,
|  | bool | expand |
| ) |  |  | `[protected, virtual]`

void Gtk::CellLayout::pack_start | ( | CellRenderer& | cell,
|  | bool | expand = `true` |
| ) |  |  |

Packs the cell into the beginning of cell_layout.

If expand is `false`, then the cell is allocated no more space than it needs. Any unused space is divided evenly between cells for which expand is `true`.

Note that reusing the same cell renderer is not supported.

Since gtkmm 2.4:

Parameters:

  | cell | A Gtk::CellRenderer.
  | expand | `true` if cell is to be given extra space allocated to cell_layout.

template <class T_ModelColumnType>

void Gtk::CellLayout::pack_start | ( | const TreeModelColumn<T_ModelColumnType>& | model_column,
|  | bool | expand = `true` |

| ) |  |  | `[protected, virtual]`

void Gtk::CellLayout::reorder | ( | CellRenderer& | cell,
|  | int | position |
| ) |  |  |

Re-inserts cell at position.

Note that cell has already to be packed into cell_layout for this to function properly.

Since gtkmm 2.4:

Parameters:

  | cell | A Gtk::CellRenderer to reorder.
  | position | New position to insert cell at.

virtual void Gtk::CellLayout::reorder_vfunc | ( | CellRenderer* | cell,
|  | int | position |

Glib::RefPtr<Gtk::CellLayout> wrap | ( | GtkCellLayout * | object,
|  | bool | take_copy = `false` |
| ) |  |  | `[related]`

A Glib::wrap() method for this object.

Parameters:

  | object | The C instance.
  | take_copy | False if the result should take ownership of the C instance. True if it should take a new copy or ref.

Returns:
  A C++ instance that wraps this C instance.
